Assisted phytoremediation of lead contaminated soil usingatriplex halimusand its effect on some soil physical properties
(Springer, 2020)
Lead is one of the most harmful trace elements found in soils. Despite reductions in environmental lead exposure, an historical lead pollution continues affecting soils in many areas. To mitigate the impact of lead, ...
Effect of iEucalyptus globullus/i biochar addition on the availability of phosphorus in acidic soil
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias Agrarias, 2017-01-01)
Phosphorus (P) is one of the primary nutrients limiting crop production. The application of phosphate fertilizers in acidic soils leads to the formation of secondary insoluble compounds that reduces the effectiveness of ...
Soil organic matter-metal interactions in Chilean volcanic soils under different agronomic management
(MARCEL DEKKER INC, 2002)
The organic matter existing in volcanic soils must be investigated not only in quantity, but also in quality in order to understand its role in soils and thus ensure adequate levels of stable organic polymers contributing ...
Sequential extraction of heavy metals in soils irrigated with wastewater
(MARCEL DEKKER INC, 1999-05)
Different chemical forms of cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), lead (Pb), nickel (Ni), and zinc (Zn) were determined in agricultural soils cultivated with lettuce and celery. These soils have been ...
Glomalin-related soil protein in a Mediterranean ecosystem affected by a copper smelter and its contribution to Cu and Zn sequestration
(ELSEVIER, 2008-11-15)
The amount of glomalin-related soil protein (GRSP), a glycoprotein produced by arbuscular mycorrhizal fungi (AMF), its contribution to the sequestering of Cu and Zn in the soil, and the microsite variation of other soil ...
Presence of heavy metals in organic cacao (theobroma cacao l.) crop
(Universidad Nacional de Colombia Sede Palmira, 2012-10-01)
The presence of heavy metals in cocoas crop is becoming a problem for farmers and cooperatives at Huánuco and Ucayali regions, Peru. In this research cadmium and lead contents in cocoa soils and leaves were evaluated. For ...
Seedling fate across different habitats: The effects of herbivory and soil fertility
(ELSEVIER, 2015)
The impact of extinction of predators and subsequent herbivore release on ecosystem functioning has been well studied in temperate ecosystems, yet we have very little information on threatened tropical rainforests. Herbivore ...
